Johnson Controls FX-PCX4711 Series, Installation Instructions Manual, Page: 6 / 22

Important: Connect 24 VAC supply power to the
controller and all other network devices so
that transformer phasing is uniform across
the network devices. Powering network
devices with uniform 24 VAC supply power
phasing reduces noise, interference, and
ground loop problems. The controller does
not require an earth ground connection.
Wireless Network Applications
The controller can also be installed in a wireless
application using an FX-ZFR1811 Wireless Field Bus
Router.
To configure a controller for use with the FX-ZFR Series
Wireless Field Bus system:
Note: FX-PCXs can talk wirelessly on the FC bus only.
1. Connect the FX-ZFR1811 Wireless Field Bus Router
to the FC bus port (RJ-12 modular jack) on the front
of the controller.
2. Ensure that the controller's device address DIP
switches are set to the correct device address. See
Setting the Device Addresses .
3. Set DIP switch 128 to ON, which enables wireless
operation on the controller.
For more information on installing a controller in a
